AT&T Announces Ruggedized Samsung Rugby 4

AT&T today said it will sell the Samsung Rugby 4 beginning later this year. Samsung's Rugby series devices are ruggedized flip phones that include push-to-talk via AT&T's Enhanced PTT service. The Rugby 4 builds on the Rugby series' basics by adding Wi-Fi and noise suppression, and improving the speaker. The Rugby 4 boasts a mil-spec rating for toughness and GPS for navigation. AT&T declined to provide pricing details, nor did it say exactly when the Samsung Rugby 4 will go on sale.
